Friedman pedals are the way to go. I have two of them and between the Dirty Shirly OD (JTM45) and the Black Eye OD (JCM800) I'm pretty set on marshall tones outside of a TSL60 combo I might want one day... Anyway. I got the BE-OD last year and couldn't be happier. When I want a Marshall Channel on my fender-amps, it's right there. The touch sensitive and control/dynamics are all there. Great pedal. The controls are very amp-like and responsive to adjustment. The Dirty Shirly is no different! Just wreaks of classic Marshall crunch and growl where the BE-OD has that Modern grind and push and just keeps on going.
